That PSU will run your system just fine. And where did you read that 64-bit uses "a lot more power"? That sounds like newspaper reporting. The same kind of "reporters" who tell people AMD chips are slow because they are clocked slower than Intel chips.

Please tell us whhere you got that from so someone who lives nearby can get over and smack them around.

The 420W PSU included in the X-QPack is a pretty good one, and will be plenty to power your system.

No, it's not. The first one died within hours of being turned on. I had to send the whole case back just to RMA the PSU. My replacement also died within hours. That's why I'm now looking for something else.

Maybe he was. I read his post early this morning when I first woke up, I really don't remember the details now.
I think what he was getting at (and what still makes sense to me) is that an Athlon 64 running together with Windows XP 64-bit will require more power than the same processor running with Windows XP 32-bit. That is a correct statement, isn't it?

Ok, then no, that isn't a correct statement in any context... power consumption is based on die size, transistor count, and other silicon processes, it has nothing to do with physical bit-size. Incidentally, 64-bit dies are only slightly larger (1-2%) than their 32-bit counterparts, mainly because of the added registers... as Sunner has already stated.
But if this person were talking about A64 X2 dual core processors (or two physical cores together as one) then it's possible, in theory, to imagine that they would consume more power.
Although, on a side note, just now looking at new reviews, it seems AMD is turning in some remarkable power consumption number for their X2 processors. So it seems, at least for AMD dual core processors, the power supply requirement pronouncements were slightly exaggerated.
